Vivaldi on the macbook pro with touchbar

I have been using Vivaldi for a long time since it was first released as a preview, I like it a lot and I think it has a lot of potentials but there are a couple of issues as to why I do not make it as a default browser on my macbook pro:

It does not support touchbar yet

The tab font looks kind of blurry - if you look at the texts on Safari, and Chrome you will know what I mean here

The last point and it is a show stopper is that it uses much more energy than Chrome and Safari
